Madrid's climatological mean daily maximum for May registers 22-25°C. A 17°C peak represents a distinct negative thermal anomaly. While a robust transient frontal passage or cold air advection could depress surface temperatures, forecasting an *exact* 17°C high, given typical diurnal warming profiles and current ensemble dispersion in long-range mesoscale models, is improbable. Probability mass distributes across a wider thermal band. 85% NO — invalid if synoptic pattern shifts to sustained polar air mass intrusion by May 5.
